About
Cassettes & Freewheels

Cassettes and freewheels for bikes are a cluster of sprockets in a range of sizes offering a multitude of gear ratios. The difference between the two is, a cassette slots onto the freehub, which has the ratchet built in and is then secured with a lockring, whereas a freewheel is a cluster of sprockets built around a ratchet and threads directly on to the hub. Cassettes and freewheels come in many ratios, close ratio is when the number of teeth increase in small increments of 1 or 2 at a time, whereas a wide ratio is when the teeth increase in larger increments of 3 or 4 at a time. Most systems will use a cassette hub as these allow for a wider bearing spacing and increased axle life, you can also fit a larger quantity of sprockets onto a cassette hub with 11 speed systems now becoming available. With cassettes you must use the appropriate spacing for your gear levers and rear mech, Shimano and Campagnolo are not interchangeable so you will need to match the cassette to your levers for smooth and precise shifting. Sram and Shimano chains and cassettes will work together as they use the same spacing.

does the job
I was just after a cheap and compatible cassette and this does the job nicely. It seems to have lasted quite well too

Perfect buy..
A perfect replacement for my other cassette which now sits on my other wheels. It is smooth and responsive with no jumping of cogs. Looks well manufactured and not too heavy.
Recommend at this price...

Sensible gearing!
The first thing I did with my new hybrid was replace the stock cassette with one of these with the 13-26T sprockets. I have no use for a 11T sprocket and this cassette gives me closer ratios and gears that I actually use! Having said that, 13-30 would be even better for hills but I don't think this combination is available.

Standard 8 speed road cassette
A standard Shimano piece of kit, well made and easy to fit. Replaced the cassette and chain on my Specialized Allez with Shimano RS11 wheels. Easy - there's nothing not to like.

Yes this HG50 cassette would be fine as replacement for your existing 8 speed cassette. A new chain is also advisable if fitting a new cassette as you may have slippage using an old chain and new cassette; http://www.wiggle.co.uk/cycle/chains/

Yes you can. Good idea to replace the chain at the same time as the cassette. Make sure you choose and 8 speed chain to run on this cassette. I recently bought this cassette and a KMC X8 93 8 speed chain and the two run great.

Answer:

Very dependant on your level of fitness, the course, what you're running up front etc...For instance, on a flat course that may have some rolling bits where you need to change down you might want to opt for a close block ratio like 12-21. You could maintain a consistent cadence over the lumpy bits and carry it well onto the flats and descents without having large jumps of 2-3 teeth in the gears. However on a hilly course you might want something bigger like a 26 on the back to spin up the climbs. Don't get too hung up on gears. On my 8 speed training bike which I have raced on I run a 12-26. I find this gives me a lot of options.If you want to see huge improvements on the bike get a mate to help with a bike fit and buy some clip on aerobars.

Are these individual cogs with spacers? Is this compatible with Campy shifters and derailers using campy spacers? I am currently running a Shimano 8-speed cassette (dura-ace?) 11 - 23 but need a lower gear like a 25 or 26.

Answers

Answer:

The main body is a fixed bunch of 6 sprockets and the last 2 are loose but there are no spacers as the side of the loose sprockets act as the spacer. You can't run campy shifters and derailleurs accurately on a shimano cassette. By the way, I just discovered that a X8 KMC chain is compatible with both campy and shimano.
